Ok ive been wondering what is EVDO REV A, ive seen alot of people talking about the update coming out soon. What does it do? Btw if there was wifi and you had good connection on the phone how fast would it be then the normal sprint internet?

Check out this link for the answer to your questions:

Out of curiosity, does Sprint offer EVDO Rev 0, or just 1xRTT? Bell offers both, and there is a remarkable difference in speed, but Rev A does not appear dramatically faster than Rev 0. Since all the Sprint users are going nuts over Rev A, I was assuming they don't even have Rev 0, but maybe I'm wrong?
Sprint EVDO rev 0 has a max cap of 1.5 mbps
Rev A has a max cap of ~ 3 mbps
I'm getting ~ 1.2 mbps on a 4+ bar signal (rev 0)
good rundown
oh yeah, Sprint also throws you on 1xRTT while you're in a call... not sure if that will change with Rev A
That's normal. Rev A won't change it, as it doesn't let you use data/voice at the same time and never will.

Hello,
I heard sprint is updating their 3G network to rev b which could provide very fast 3G coverage - faster than 4G in some cases. Anyone know if the new Epic Touch 4G does rev b? I know the evdo 3d can do rev b.
Yes it will.

Thanks - I couldn't find anything concrete in the specs on the ET4G. All of the specs sheets I could find on it said EV-DO Rev A.
Nice.
Swyped from my HTC Evo 4g via XDA Premium App. Soon to be swyped from my Samsung Galaxy SII Epic Touch on Tuesday.
This isn't confirmed yet, only a rumor. I sure hope it is true though!

yes! I saw 1600kbps download on 3g today...repeated multiple times. Once I left the area it went back to normal speed, so the tower I was connected to must have the latest and greatest. It wasn't that fast 2months ago in the exact same spot.

Is that under optimal conditions. IE nobody connected to the tower? When I go out to the country (I live in farming area) I get decent speeds, but as soon as I get into the city data speeds get miserable. This was in the middle of the city.
I saw some other strange things this evening near my house where I get almost no service...I think they are gearing up for the iphone.
According to this it will

I've always wondered tho.....those speeds are they best case (1 person connected) or are they realistic (1,000 phones connected?)?

Interesting that you say that... When I go to my cottage up in the middle of the woods of northern Wisconsin, I get 3G roaming from Alltel (I think CellOne bought those particular towers, not Verizon), I get FAR faster data speeds than I do in the middle of Milwaukee.
Bit confusing this thread sez it suppots revb but then this thread:
http://forum.xda-developers.com/showthread.php?t=1272773
sez no rev b. Wonder which way it will end up ...
So buzz has started to fly around about Sprint possibly announcing Oct 7th implementing EVDO Rev. B on its network. I'd imagine anyone suffering from poor 3G data speeds would be interested in this, assuming it holds any water at all.
So I was looking at iFixit's teardown, and it lists the CDMA chip in this phone as the Qualcomm QSC6085 CDMA Processor. From what limited information I can find, this chip is not capable of EVDO Rev. B. Some things I've read seem to indicate it's simply a software thing, but I have to think the hardware in the device has to be able to take advantage of it. Everything I can find about the QSC6085 says it doesn't.
Now, I'm no engineer, nor do I know very much about CDMA data technology, but can anyone here shed some light on whether or not this phone would be capable of EVDO Rev. B if it were indeed implemented by Sprint? Could Samsung send out an OTA Update that would enable it?
I know this is all dependent on Sprint actually implementing it, which is questionable at best, but I'm trying to think ahead.
I don't know much but according to them it will..

Does Rev B allow simultaneous talk and data?
if it is true, I'm wondering why the he'll they haven't been implemented this long ago..

It was a choice. Invest in 4G network, or jump into "3.5G" aka EvDo Rev B. I'm sure you know which one they went with.

Sprint has NEVER talked about deploying EVDO Rev B.
They have talked about upgrading all of their base stations, radios, and antennas.
Since they are deploying LTE and WiMAX, it makes sense for them to deploy EVDO Rev B since the iPhone isn't going to have LTE radio. This gives them a nice competitive edge against Verizon.
The great thing is, all of their radios are going to be software programmable and mounted on the actual tower. This will let sprint just swap out base station cards when they phase out wimax, etc. Not having to deal with new radio hardware will allow sprint to keep it's network much more modern, esp with a flat IP-based architecture.

Right. They never announced it because they never went with it.
If Sprint can throw out EvDo Rev B before Verizon does, they could see a major increase in customers.

This. The iPhone not having a 4G technology, plus the fact that it is SDR (Software Defined Radio) makes me feel like there is a good chance EVDO Advanced and 1x advanced, allowing Voice and Data simultaneously will be implemented via software on the base stations.
Probably will be a radio flash update for phones on the phone end to support these new protocols.
SO if sprint does setup this network rev b is the Epic touch capable of taking advantage of it?

There's sites (such as Gizmofusion) stating that it will. It's all whether or not it's software dependent. If it's hardware dependent, then we wont be able to use it.
so if its a hardware thing then the epic touch wont be able to use it but then what will happen with the epic touch no more connection or is sprint still gonna have the rev a and wimax connections available for all older phones
The evo 3d supports it, so surely the epic 4g touch does....

I'm not so sure about that. The EVO 3D's cdma chip is built onto the Qualcomm's Snapdragon SOC that the phone uses. It uses the MSM8660, with MSM being "mobile station modem", which I believe was the successor chipset line to the QSC chipsets and added EVDO Rev. B support. The fact that Qualcomm built the entire SOC for the EVO 3D might have been an advantage in this case.
Here is QSC6085's description from the press release back in 2007:
The QSC6085 solution is pin- and software-compatible with QUALCOMM's
previous-generation QSC products, including the QSC6055(TM), QSC6065(TM)
and QSC6075(TM), allowing device manufacturers to leverage existing
hardware platforms and software applications for a comprehensive portfolio
of handsets across CDMA2000, EV-DO Rel. 0 and EV-DO Rev. A networks.

If the Epic Touch indeed CAN'T connect to Rev B, I wonder if the "old" CDMA chip was used to cut costs in order to meet the $200 price point for Sprint?
Hello guys,
I've read on the spec sheet and knowing that OG can use the rev b channels, is it true? The reason i asked this because in my country the rev b channel offers more speed than rev a and we dont have the 4g data connection, and if its true, i wonder how to unlock it?
(And i know my friend evo 3d can be unlocked in order to receive the rev b channel)
Sorry for my bad english

yeah, but still no clue on how to unlock it,
Can someone tell me the difference between, 4G, LTE, WIMAX and GS3? What does the GS3 have and on my previous HTC phones, there was a toggle/setting to turn off the 4g Radio. I don't see anything but "mobile data". Is that 3G, 4G or both?
Bob
4g and wimax are the same thing which is 3g revision b or c depending on carrier. Standard 3g is called 3g revision a. But the FCC gave them permission to call it 4g since it data speeds can go up to 9mbits per second. LTE is the true 4g. LTE stands for long term evolution. Its data speeds can go up to 40mbits per second. So if you see carriers saying 4g without LTE after 4g they are technically lying to you. Gs3 I'm assuming your talking to Samsung galaxy s3, it just has the ability to use all of them since its multi carrier.
Mobile data is both. 3g and 4g and 4g LTE are mobile data. So if you turn that off all data will be turned off. Some phones don't give you the toggle to turn off 4g but I think there are custom roms that have that feature.
Sent from my Incredible 2 using xda app-developers app
Mobile data is any internet connection, however it depends on the rom as to whether hitting a widget that says that will toggle 4G AND 3G as some roms (like stock HTC ones) provide separate toggles
Wimax is a type of 4G and so is LTE, if you want more specifics I would start with Google
The s3 has 3g and 4g lte radios only, no wimax and if your not in a lte area you will only get 3g speeds which are slow. I live in Illinois and there's 4g lte in most areas.

Please tell me this was just poorly worded and not your entire take on the 4G/Wimax/LTE situation. This post made my head spin, and now I need to write a long post explaining everything that's wrong.
First of all, there is no "3G Revision B" or "3G Revision C", let alone "3G Revision A". That's ridiculous. 3G is a marketing term. There are several 3G technologies, including EVDO (which Sprint and Verizon both use for their 3G technology) and HSPA (which AT&T and T-Mobile use). There is an EVDO Revision B and C, but Sprint uses Revision A. No one uses EVDO Revision B or C. Either way, EVDO Revisions B and C are entirely unrelated to either Wimax or LTE.
The FCC didn't give anyone permission to use the term 4G for anything. They don't care what you call the technology as long as it complies with FCC regulations. The rest is just marketing speak, and the FCC wants nothing to do with it.
Wimax and LTE are both types of 4G. There is no "true" 4G in this case. 4G is just a marketing term for what they consider the 4th generation of mobile data protocols. 4G and Wimax may be used interchangeably, and so may 4G and LTE. If you're being specific about one, be specific about the other. Saying things like "4G or 4G LTE" sounds stupid to me when the person means "Wimax or LTE". It's like saying "Do you want cookies or chocolate chip cookies?" Either way, you're getting cookies - one's just more specific than the other.
Other carriers do not need to put LTE after 4G in their marketing. No one but you decided that LTE was "true" 4G over Wimax. Both are 4G (barely), so it doesn't really matter which 4G technology they use. It's still 4G. No one is lying just because they don't specify which type of 4G they use, which is a moot point anyway, since Sprint is the only carrier that used Wimax for their 4G technology. It can just be assumed that 4G == LTE in other companies' marketing. Likewise, it's not lying if Sprint says "4G" instead of "4G LTE" either. It's just marketing.
As for speeds, neither protocol is limited in the way you mention. Wimax as a protocol is in no way limited to 9Mbps speeds. First, Sprint's Wimax could go much faster than 9Mbps easily. Second, the speeds are not limited by the protocol. They are limited by the implementation of the protocol. It's possible to hit 40 or 50 Mbps with Wimax if you have enough spectrum and backhaul available. Likewise, LTE is not limited to 40Mbps either. If Sprint had the spectrum and the customer base, they could roll out LTE that goes to 150Mbps or more. It just depends on how they scale it.
And finally, the GS3 does not have the ability to use "all of them". The Sprint GS3 is not compatible with Wimax at all - just 1xRTT, 1x-Advanced, EVDO Revision A, and LTE. And that has nothing to do with it being multiple-carrier anyway. If that were the case, we could use AT&T or T-Mobile's HSPA+42, and they could use EVDO Revision A, but neither of those things is possible IRL. Samsung made the Sprint GS3 compatible with the technologies Sprint was using, and likewise for all the other carriers' models. There is no need to look any further into it than that.
